Body material: carbon steel, stainless steel Suitable medium: acid, alkali strong oxidizing medium Product Name: Board lining Product Details: composite panels lining process, because of their advanced technology, reliable quality assurance, can effectively solve the major problem of the chemical industry to clean, temperature, vacuum-resistant, corrosion-resistant, and in the international arena has been widely used in the country are also increasingly subject to the user's attention. At present, the use of polysilicon, silicones, semiconductor, fluorine chemical industry, praised by users. Compared with the general fluorine plastic lining, composite panels lining equipment has its unique advantages:? 1. The limit can be resistant to vacuum at its allowable temperature, can withstand high vacuum. General fluoroplastic lining equipment almost can not operate vacuum (vacuum). Some domestic manufacturers manufacture PTFE wrapping lining steel net to strengthen the equipment, the ability of a certain degree of negative pressure operation, but because about 10 times or so well-known linear expansion coefficient difference between steel and plastic, so its service life is often very short and very unreliable. Some other small articles to be to improve their ability to resist negative pressure by increasing the thickness of the liner. However, it can not solve the problem of negative pressure-resistant fluoroplastic lining equipment fundamentally. The composite sheet lined with craft, due to the connection with an adhesive plastic layer and the steel substrate layer, it is the material between the two huge linear expansion coefficient difference decomposition limited within a small range, so can resist high negative pressure. This makes some require both strong corrosion resistance, and resistance to vacuum requirements, and the use of temperature conditions below 150 ℃, the composite panels lining the process to become a best choice. 2.? Allows the use of higher temperatures in the same conditions, can withstand a higher continuous use temperature. The actual maximum continuous temperature PFA / PTFE composite panels lining the device up 200 ℃, PVDF composite panels lining the maximum temperature of 150 ℃, close to the temperature limit of the material. And if other processes in its continuous use temperature limit, due to a variety of factors, will make life greatly reduced. 3.? Restrict geometry processing equipment from conventional isobaric, winding, roll and other processing equipment size and shape easier restrictions. For example, some tower equipment longer, even up to the manufacturing capacity, due to the fluorine plastic linear expansion coefficient of about 1 × 10-5mm / (mm · ℃), the length is too long, is bound to increase the amount of linear expansion, eventually leading to fatigue cracks and failure. There are some special structures, can not use conventional manufacturing processes. And because the composite panels lining process will be broken down into different parts of one sheet, or a combination of components for welding, so it is easy to complete. 4.? Can be used for the most demanding quality electronics, semiconductor and other industries, such as ultra-pure pressure, winding, roll, etc. due to the influence of the material itself and the process of its lining is difficult to achieve some of the harsh chemical equipment industries. The composite plate lined with ultra-pure plates, some of the key steps can be done in the appropriate level of the clean room, and its products meet the electronics, semiconductor and other requirements of super pure industry requirements. So the process has increasingly shown its unique advantages in these situations. ?
